I need help here please..! I took a picture of the Multi -Step equations..!

Answers

There are 8 problems in the picture. What you need is for someone to give you
some tips and solve one or two of them.
Giving you a bunch of answers and nothing else does NOT help you.

Here are my tips to you:

A). You're always trying to find the number that the unknown letter must be equal to,
in order to make the equation a true statement. That's the solution to the equation,
and the 'answer' to the problem.

B). Always do what you have to do in order to get the letter all by itself on one side.

C). Whatever you do to one side of the equation, you must do to the other side.

==========================================

Examples, from the picture:

#3: 8x - 2 = -9 + 7x What can you do to get the 'x' all alone on one side?

Subtract 7x from each side: x - 2 = -9

Add 2 to each side: x = -7
===========================================
#2: 6 = 1 - 2n + 5

Combine the 1 and the +5 on the right side: 6 = 6 - 2n

What can you do to get the 'n' all alone on one side?

Subtract 6 from each side: 0 = - 2n

Divide each side by -2 : 0 = n
===========================================
#5: 4m - 4 = 4m

Subtract 4m from each side: - 4 = 0

There is no number for 'm' that can make -4 equal to zero.
So this equation has no solution.
(That's OK. Not every equation must have a solution.)

2 (x-4)=8
help me solve step by step

Answers

2(x-4)=8

Distribute

(2)(x)+(2)(-4)=8

2x-8-8

Now add 8 to both sides so you can find the value for x

2x-8+8=8+8

2x=16

Divide both sides by 2

2x/2=16/2

x=8

I hope that's help !

Which of the following shows the correct factorization of x3 - 5x2 - 14x?A. x(x + 7)(x + 2)

B. x(x - 7)(x - 2)

C. x(x + 7)(x - 2)

D. x(x - 7)(x + 2)

Answers

So, just a note of formatting, to indicate something is an exponent of something else, use the carat (^) sign
for instance
x^3 means x cubed. x3 means 3x.
Anyways, though, let's factor.
You can factor out an x from each variable.
x(x^2-5x-14)
Now, to factor this, think of what will add to -5, and multiply to -14.
-7 and 2 work.
So, this factors out to
x(x-7)(x+2)
Choice D is the correct factorization.

fifteen percent of the workers at nationwide industries earn minimum wage. if 24 workers earn minimum wage, how many total workers are there at nationwide industries?

Answers

if you do 100 divided by 15 times 24 you get 160

Let the total number of workers be x

Since its given in statement, that 15% of workers earn minimum wage and that is equal to 24.
i.e 15 % of x = 24
x*15/100 = 24
x = 24*100/15
x = 160
therefore total number of workers are 160
